North Korea lack of power

I have a theory that the whole media bluffs America on a steady-going basis in order to sell more things and get more viewers and higher ratings. I believe that North Korea could not compete in many things and military strength is 1 of those things I do not see them having. I do not think they could compare to South Korea let alone USA or Japan or China or anyone near them. This whole North Korea constant story situation overshadows Iran and its real power and the real issues in the World in order.
